Abstract

This paper presents a laser based machining system, especially designed for the production of micro prototypes. The principle work concept of the machine is similar to conventional rapid prototyping (RP) techniques. According to slices of a 3D CAD data file, the part is created layer by layer from the bottom up to the top. However, an optimized design will extend its application to the production of prototypes in the range of 8 mm³ to 125 cm³ but with a resolution of 20 micrometers in all directions. Different to other existent machines is the modular construction, which allows the use of different materials and laser sources with little effort. Thus, stereolithography and selective laser sintering processes can be performed on the same machine. The machining system consist of 5 modules, machine frame, housing, optic, process and software, all designed to meet the requirements defined by a questionnaire among industrial RP job-shops. Pre-investigation have confirmed the resolution in x, y direction.
